找不到有效的 Docker 环境

Question

我刚刚使用 Kotlin + Gradle + REST 从https://code.quarkus.io下载了一个新项目，并尝试执行./gradlew quarkusDev 并遇到以下错误：

除了构建器提供的框架之外，我没有添加任何代码，如上所述，我使用 colima 而不是 docker。

Answer 1

在日志中，您可以看到 Quarkus 正在尝试在以下位置查找 docker 套接字：/var/run/docker.sock

但是当使用 Colima 时，路径是不同的：

v0.3.4 或更早版本 -> Docker 套接字位于 $HOME/.colima/docker.sock

v0.4.0 或更新版本 -> Docker 套接字位于 $HOME/.colima/default/docker.sock

也可以通过检查状态来检索它 colima status

由于您当前使用的是 Colima v0.5.4，我想 Quarkus 应该查看 path $HOME/.colima/default/docker.sock。但为了更加自信，只需跑去colima status拿真正的。

正确配置 env，以便 Quarkus 可以找到 Docker .sock

您必须通过运行以下命令来指示它：

export DOCKER_HOST="unix://${HOME}/.colima/default/docker.sock"

或者禁用 devServices

您可以禁用 devServices，因此 quarkus 将不再需要 docker 来启动：只需将其添加quarkus.devservices.enabled=false到您的application.properties
